Beşiktaş are monitoring the situation of Casa Pia's 27-year-old Cameroonian defender Duplexe Tchamba, who is in the final year of his contract and could be available on a free transfer at the end of the season. The player's future is considered open as Casa Pia's administration currently deems it too early to start talks about a possible renewal. Other Turkish clubs are also tracking the defender, including Trabzonspor, who are similarly considering a zero-cost deal. Galatasaray is another interested party, having previously tried to sign Tchamba in 2022 when he was playing for Sonderjyske in Denmark. According to Transfermarkt, the player has a current market value of €1.00m.
